The invention relates to new and useful improvements in mine carsadapted for use in what are commonly known as low vein mines,-that is,mines in which the seam is relatively thin and a few inches inthicknessfrom top to bottom,-though it is adaptable Jfor `use in other places bymere change in dimensions.

As shown in the drawings, the car is designed primarily for use in acradle dump, though with slight modification within lthe disclosureofthe prior a rt an end gate may be substituted for either 'of the endwalls shown and the car used in a tipple or end dumping device.

Fig. 1 is a side elevational view of a mine car embodying the presentinvention;

Fig. 2 is an inverted plan view of the major portion of said car; and

Fig. 3 is a transverse vertical sectional Viewv taken on line 3 3 ofFig. 2. t

Referring to the parts, it will vbe observed that the car oor comprisesplanks "5,l 6a and 7a intermediate the angle sills 13 and 14, whichplanks and sills rest upon the bolsters 18a which in turn rest upon andare secured to conventional journal or axle boxes 50 (see Fig. 2)through which the axles 21 extend; said axles terminating in the wheels20, as in -usual in this type of construction. As shown, the holsters18a are of channel section, and thus serve as axle housings. The planks5, 6", 7a are secured to the holsters 18aL by' bolts 51 which passthrough the horizontal web portions 52 of said holsters. Besidestlieplanks 5a, 6a and 7 in the center, the floor also includes planks5", 7", and metal plates 18", outside the sills 13, 14. At their outersides or edges, these outer floor portions may be reinforced with sidesill angles 36.

Manifestly, the wheels 20. which are intended to run on the conventionaltracks, support the axles 21, which in lturn support the journal boxes50; and the journal boxes -underlie and support'the longitudinal sillsor angles 13 and 14. These 13 and 14 not only perform the usual functionof sills, contributin to the support of the iloor between and yond theaxles 21, 21, etc, but they also extend beyond the ends of the car bodyand serve as stieningmembers for bumpers or buffers 10, 11 formed byextended end portions of the floor, which portions enclosed between theprojecting ends of said members 13, 14. The bumpers 10, 11 are shown asof conventional type, comprising the ends ofthe door boards 5, 6a, 7beyond the car body, the'fller members A, and the sheet metal sheathing12, which laps said parts and is secured to them by through bolts orother connections (not shown). The fillers A are backed'` up andstifened by abutments formed by transversely extending angles B, securedto the under side of the car floor and also riveted to the angle sills13, 14. Accordingly, the sills.13, 14 assist the buffers 11, 12 intaking end shocks when cars are coupled together.

As shown in Fig. 3, the angles 13, 14 lie in the longitudinallyextending floor plank- `ing with their vertical' flanges 13.a and 14ainterposed between adjacent planks and the flanges 15a and 16 beinggained ,into the bottom portions of some of the planks. It will beobserved lthat between the wheels of Figure 3 there are three planks 5a,6" and 7a shown, with portions of other planks 5" and 7", and that thestiening angles 13 and 14 are interposed between the planks 5a and 5"and the planks 7'i and 7".

It will be observed that if extended in a single plane, the sideportions of the door including the planks 5" and 7" would intersect theupper portion of the car wheels, but that the plates 18" are pressedupwardly to clear said wheels. It will be seen, therefore, that the carfloor consists essentially of a main central portion or section,reinforced and stiffened by the sill angles 13, 14, and equipped withthe central buffers-10, 11 at its ends, and also side sections extendingoutward from said central section, with which side sections are combinedthe wheel hood sections 18".- The normal plane of the side floorsections extends outwardly and intersects the plane of the carwheels.The plates or side floor sections which lap the central floor sectionare rigidly connected thereto in any suitable manner, as by bolts 25.Cross-braces or tie-straps such as 21", 21", 22", 23", and 24" areprovided for the floor planking, and extend beneath the side sections aswell as the center sections. 26 bolted to the straps'and to the doorplanking extends centrally of the car, substantial-f ly to the outersides ofthe bumpers 10, 11; as shown, it is gained into the uppersurface Abar,

of the planking. Near each end of this bar 26, a coupler bar 27 isriveted thereto.

As the car Yshown in Figures 1, 2, and 3 is intended to be used with arotary dumping device, it is equipped with flanged depending members 30at each side and near each end of the body, which are intended .tointerlock with corresponding elements in the dumping cradle, not shown.As the lading is not obliged to slide longitudinally of the floor indumping, itis permissible to place reinforcements for the car bodywithin the same. These reinforcements comprise stiening angles 31 which,with the tie-straps hereinbefore referred to, serve to reinforce thebodyV of the car. Additionally, gussets 33 are connected with theinwardly disposed flanges 34 and with the vertical dan es 35 of thevertical side angles and the ang es 31 at convenient intervals along thelength of the car whereby a rigid structure is provided.

As a whole, it will be seen, the floor extends in nearly a horizontalplane. As already mentioned, the ioor is reinforced at its outer sidesby the side sill angles 36. f

The door is amply braced'andmade rigid, transversely, by the straps 21a,2lb, 22h, 23", 24:b and the angles 31, which latter are preferablybolted to the straps through the planking, as shown at 32 in Fig. 3, aswell as by the end walls, which are connected to the side walls.Longitudinally, 4likewise, it iseii'ectively braced by the sills`13, 14,and

36. The straps and the transverse members 31 also serve (as well as theends) for supporting the outer floor sections from the sills floorcomprising a plurality of longitudinally extendlng planks anda'plurality of longitudinally extending angles between .and lapping saidplanks and connected thereto with a sheathing of metal enclosing one endof said planks; the planks, angles' and sheathing beingl connected and'adapted to cooperate in reslsting buiing Stresses.
